Flotation Cells (Froth Flotation) were developed to separate and recover high value Sulphide ores from low grade ore bodies. The ore is crushed and milled at the concentrator in a process known as comminution, where the mineral is in suspension in slurry. The particle size for mineral being recovered is generally less than <0.1mm.

Pyrrhotite floats best in acid circuits. The pH range for flotation for gold sulfide ores containing pyrite and arsenopyrite is generally between 7 and 9. Flotation may be carried out at higher pH values of 9–10, since this favors the depression of talc minerals and avoids the use of expensive gangue depressants.
